Quantitative Elektronenstrahlmikroanalyse und Zyklotronresonanzmessungen an Wismut-Antimon (Bi1−xSbx)

For the investigation of the electronic properties of bismuth-antimony single crystals the analysis of their chemical composition is important. For this te Electron Microprobe Analysis is a suitable method. In general the quantitative Elektron Microprobe Analysis requires to take into account various influences. This is possible by correcting calculations on the basis of theoretical models. For the reproducibility and the comparability of analytical results information is necessary on conditions of measurement and on theoretical corrections. In this paper an investigation is made, under which conditions in the analysis of bismuth-rich bismuth-antimony alloys the correction can be neglected. The successful utilization of the Electron Microprobe Analysis for the investigation of the dependence of the band structure of Bi_1−xSb_x on the antimony concentration x is shown by the example of the measurements of cyclotron resonance.
